Monitor won't display the correct resolution after upgrading to High Sierra

I just upgraded to High Sierra and now my monitor (NEC MultiSync PA272w) won't display at it's optimal resolution (2560x1440). Under displays in system preferences there is no option to use that resolution under scaling. The highest it goes is 1920x1200 which looks bad on my display. Everything was fine under Yosemite, but I don't really want to go through all the hassle of downgrading the OS. Any ideas?

I had the similar problem with an apple 30 inch Cinema Display x800 instead of x1600. Fix was to pull the DisplayPort cable out of the computer while live then put it back in; what effectively happened was the chance to verify and repair its profile.

Are you connecting via HDMI, Thunderbolt etc? I use a dual link DVI for my second display to be able to boot at 2560x1440. If not it boots 1920x1080. Just by chance choose a different resolution, reboot and see if the 2560x1440 then shows up. If not you need a new adaptor. Look on apples website under accessories.
